Im not sure what to do and now getting worried she might not make it. Yellowing/browning and dying leaves that seemed to start on all fan leaves maybe starting towards the bottom. Last time ph runoff was 6.49 and a 900ppm after feeding. Not sure if it's a lockout as pH was low 6's earlier and now up or possibly salt build up or she's hungry? I want to feed but worried I'm having other issues. Fox farm trio on a quarter dose schedule if any one has any advice
